Can someone please help with this ?

    -9n+20

This is the same as 20-9n

================================================

Explanation:

The jump from 11 to 2 is "minus 9"

The jump from 2 to -7 is also "minus 9".

Assuming this pattern continues on, we have an arithmetic sequence with

The nth term can be found like so

Let's check the answer by trying n = 3

This shows the third term is -7, which matches what the original sequence shows. The answer is partially confirmed. I'll let you check the other values of n. You should get 11 when trying n = 1, and you should get 2 when trying n = 2.

Step-by-step explanation:

Given: The lengths of the parallel sides of the trapezoid are 14 ft and 24 ft. The height of the trapezoid= 12 ft.

We know that area of trapezoid is given by :-

, where a and b are the parallel sides and h is the height of the trapezoid.

Now, the area of the trapezoid shaped stage is given by :-
